The ornamental design for a speakerslectern, as shown and described.
FIG. 1 is a perspective view of a speakers lectern showing my new design.
FIG. 2 is a perspective view looking toward the speakers lectern from a
point between the top and bottom thereof, so that the upper surface of the
bottom is illustrated and the undersurface of the top is illustrated.
It should be understood that the two opposite edges, not shown, are
identical to the two edges illustrated, while the flat bottom surface of
the speakers lectern is plain.
